Title: Unit and method for heating ferrous scrap mixture before feeding it to metallurgical furnace
IPC: F27D3/10
Filed: 1998-11-26
Abstract: Ecologically friendly and highly energy efficient, autonomous, air-tight, self-charging scrap preheating apparatus and closed-circuit process system, for semi-continuous charging of cold charge - reasonably sized-prepared ferrous scrap mixture - via integrated inclined scrap bin elevator, stepped preheating and delivering of preheated charge into adjacent, in tandem operating, sealed metallurgical-electric arc furnace, using primarily sensible and chemical heat of the hot waste gases from the metallurgical-electric arc furnace, with hot gases entering the preheating apparatus at the top of the main vertical preheating chamber of prismatic form and having a converging bottom and one or more scrap gravitational descent controlling mechanisms. Internally hot gases are exhausted downwards and therefore flowing concurrently with the descending scrap resulting in gradual, highly efficient heat transfer with reduced scrap oxidation. Descending scrap is dispensed through the opening in the converging bottom of the preheating apparatus into discharging mechanism consisting mainly of a reciprocating trolley-trough, and a reciprocating ram. Optimally preheated scrap is force delivered via inclined charging mechanism into adjacent, in tandem operating, metallurgical-electric arc furnace, through the opening in the shell side wall or roof. The used off-gases are exhausted from the converging bottom of the preheating apparatus and routed into the final post-combustion chamber serving also as dust catcher and drop-out box and located in-line under the preheating apparatus. Off-gases are leaving the preheating apparatus with their temperature in the range above critical value required for burning-cracking of undesirable volatile hydrocarbons including dioxins and furans. Venturi scrubber system rapidly cools the off-gases below their lower critical temperature and exhaust them. Before discharging into atmosphere, final cleaning-scrubbing of the off-gases takes place in a centrifugal cyclone type separator or satisfactory bag house.

Abstract: FIELD: veterinary medicine. SUBSTANCE: method deals with resection arthroplasty of hip joint and could be, also, applied at surgical treatment in case of tumors both in caput and cervix of thigh bone, hip joints' dysplasia and coxarthrosis. One should carry out resection arthroplasty of hip joint in dogs due to linear cutaneous incision, cranial access by Archibald et al. , cross-sectional dissection of cranial capsular part of hip joint against the site of fixation to pelvic bones up to the cervix of thigh bone, and due to osteotomy of caput and cervix of thigh bone at the level of a line connecting both the greater and lesser trochanters in thigh bone, then comes layer-by-layer closure of wound. Moreover, linear cutaneous incision at craniolateral access is made at 4-8 cm distance, proximal part of musculus vastus lateralis should be dissected at 2-5 cm distance against underlying thigh bone, then, via caudal capsular part of hip joint one should apply P- shaped sutures free ends of which should be sutured through proximal part dissected from thigh bone, musculus vastus lateralis; by tightening, in turn, P-shaped sutures one should transpose the muscle between pelvic bones and thigh bone. The suggested method shortens the duration of operation, decreases its traumaticity level, prevents sciatic nerve lesion and shortens the terms for restoration of limb's motor function. EFFECT: higher efficiency of resection arthroplasty. 2 dwg, 2 ex
